Thrush horror sounds

I recorded this bizarre bird singing in the woods late in the evening. It's an amazing mixture of sounds, including what sounds like a mobile phone and a lorry reversing. I think it's a thrush but I'm really not sure:

(46 second clip, with the silent sections removed, background noise removed, and the different sectioned normalised so that all sounds are roughly the same level of loudness)

You know what I'm going to do now; slow it right down.

At 16% of pitch and tempo it becomes something quite new, and quite disturbing I think. At 4 minutes and 6 seconds it's rather long, but stick with it if you can because each section is different and the effect is cumulative...

Hi!
I've just started taking an interest in bird song - because I'm woken up most mornings by one just like this in our garden in Hamilton, New Zealand. In my ignorance I didn't know what it was, but then saw the little chap, high in a Kauri tree towards the back of our house.
Ours adds in a miaou, miaou, miaou; pretty bird, pretty bird set.
Now I have to find out how to record it...

Hi Steve, thanks for popping into 4AoS. Even a mobile phone can record half decent bird song, if the notes aren't too high. Have a go and send it over here and I'll post it!
